WARNING:
!
Use extreme caution when installing or removing an outdoor
!
antenna. If the antenna starts to fall, let it go! It could contact
!
overhead power lines. If the antenna touches a power line,
!
touching the antenna, mast, cable, or guy wires can cause
!
electrocution and death. Call the power company to remove the
!
antenna. DO NOT attempt to do so yourself.
WARNING:
!
Outdoor antennas must be properly grounded to prevent
!
static buildup and lightning damage. Article 810 of the National
!
Electrical Code, ANSI/NFPA 70, provides information about
!
proper grounding of the antenna mast, connection of coaxial
!
cable to an lightning arrestor, size of grounding conductors,
!
location of the lightning arrestor and connection of grounding
!
conductors to grounding electrodes. Additionally, you may wish
!
to disconnect your radio from the outdoor antenna during
!
electrical storm activity to prevent damage. The diagram below
!
provides an example of a proper antenna grounding system.
